Tonight on NBCSN, it’s the Philadelphia Flyers hosting the New York Rangers starting at 8 p.m. ET. Following are some game notes, as compiled by the NHL on NBC research team:

— Philadelphia’s win Sunday snapped a nine-game losing streak at Madison Square Garden. The Flyers now return to Wells Fargo Center, where they took both games from the Rangers this season and four of their last five dating back to last season. New York last won in Philadelphia March 26, 2013, a 5-2 victory.

— Of the 33 times the Flyers have been tied at 1 in a series, they have won 17 of those series, and lost 16. Game 2 has often been a good indicator of Philadelphia success in the playoffs: when the Flyers win Game 2, they have gone on to win the series 30 of the 37 times, regardless of the Game 1 result. The Rangers have won eight of the last 12 playoff series in which they split the first two games, including five of the last seven playoff series in which they split the first two games at home.

— The Rangers started this season playing their first nine games on the road due to Madison Square Garden‟s renovation project, getting off to a 3-6-0 start. But in their final 32 road contests, the Rangers posted a 22-8-2 record to finish 25-14-2 on the road this season, setting a franchise record for road wins in a season. New York was one of three teams to record at least 25 road wins this season (Colorado, Anaheim) and had the most road wins in the Eastern Conference. The Rangers’ 52 road points this season rank second in franchise history (2011-12 – 53).

— The Flyers overcame an early 2-0 deficit in the first period to win Sunday and are one of six teams this postseason to come back and win after trailing by two goals. During the regular season, the Flyers came back to win after trailing by two goals on eight occasions. It was also the sixth time in the last seven playoff years that the Flyers won a game in such a fashion, tying them with the Bruins for the most over that span. All six of Philadelphia’s two-or-more-goal comeback wins in the playoffs since 2008 have come on the road and prior to Sunday‟s win, the club‟s last playoff victory when trailing by two goals was April 13, 2012 when they overcame a pair of two-goal deficits to win 8-5 against Pittsburgh in Game 2 of the Eastern Conference Quarterfinals.

— Flyers goaltender Ray Emery, who has been filling in for Steve Mason (upper body injury) and who
will start Game 3, started in back-to-back games for the first time this season, earning his 21st career playoff victory and his first in exactly three years since helping Anaheim defeat Nashville April 20, 2011 in Game 4 of the Western Conference Quarterfinals, 6-3. After allowing two goals within the first 10 minutes Sunday, Emery did not allow another goal. Mason said Monday, “The way [Emery’s] playing, there’s no hurry. He’s the reason we won yesterday, so, even if I was ready, there’s no reason to take him out right now.”

— Rangers forward Martin St. Louis opened the game’s scoring in the first period, netting his first playoff goal for the Rangers after tallying 33 during his tenure with the Tampa Bay Lightning. His 34 career playoff goals ranks 13th among all active NHL players. St. Louis has 7 points in his last 4 games dating back to the regular season.

The New York Islanders made a splash on Friday, signing veteran forward Cal Clutterbuck to a five-year, $17.5 million extension — one that carries a $3.5 million average annual cap hit through 2023.

Clutterbuck, 29, has two goals and nine points through 25 games this year, while averaging 15:26 TOI per night (his highest average since joining the Isles four years ago). As per usual, he leads the club in hits — one of the staples of his game — and serves as one of the club’s alternate captains.

This new contract represents a nice raise for the former Minnesota Wild man. His last contract, set to expire in July, was of the four-year, $11 million variety, and carried a $2.75 million cap hit.

This contract also resembles the one GM Garth Snow gave another of the club’s role forwards. This summer, Casey Cizikas signed a five-year, $16.75 million extension — one with a $3.35 million hit — despite the fact he’d never scored more than 30 points in a season, or averaged more than 14 minutes of ice time.

This style of spending — along with splashes made for free agent disappointments Jason Chimera and Andrew Ladd — is sure to raise some questions. The Isles opted not to spend that money on retaining two of their key players from a season ago, Frans Nielsen and Kyle Okposo, and the club has struggled to find its form through the first quarter of this year.

“We’re not going to give out any numbers now,” NHL commissioner Gary Bettman said yesterday, per Yahoo Sports. “The cap could range from where it is now to a couple or so million up, but we’re all going to have to focus on what makes the most sense moving forward.”

The salary cap only went up slightly for the current season, from $71.4 million to $73 million. The only slight increase was due to the lower Canadian dollar, which negatively impacted last season’s league revenues by “$100 or 200 million,” Bettman said earlier this year.

The loonie has been holding relatively steady for around half a year. It’s currently worth $0.76 USD and has been helped by the recent oil rally.

A flat salary cap would be bad news for big spenders like the Chicago Blackhawks, who still need to get Artemi Panarin signed to an extension. The Los Angeles Kings could also be forced to make some tough decisions, as they’ve got Tyler Toffoli and Tanner Pearson in need of new deals. Ditto for the Pittsburgh Penguins, who have key RFAs in Brian Dumoulin, Justin Schultz, and Conor Sheary.

Henrik Lundqvist has set such a high bar that his 12-8-1 record with a .912 save percentage is cause for great concern these days in New York.

That his backup, Antti Raanta, is 6-1-0 with a .932 save percentage only contributes to that concern, because if Raanta can manage those numbers, what’s Lundqvist’s excuse?

“I feel like I’m tracking the puck well, moving well,” Lundqvist told the Daily News. “It just comes down to some bad decisions at times that cost me.”

Indeed, December has not started well for The King. He’s allowed 10 goals in three starts for a save percentage of .894. In Tuesday’s 4-2 loss to the Islanders, his decision to poke check a loose puck led to the winning goal by Andrew Ladd.
